Consider following fig, which applies to a fed-batch system.

                           

Assume at t = 0, V = 100 l, X = 2 g/l, m = 1 h-1 , S0 = 4 g/l, and S = 0.01 g/l. V is increased at a constant rate such that dV/dt = 20 l/h = F (or flow rate) and X is constant at all times. What is µ at t = 5 h?
